Data Collection Endpoint should disable public network access

High Azure General dce-no-public-access

Applies to

Microsoft.Insights/dataCollectionEndpoints

What CGPulse checks

A resource passes this rule when publicNetworkAccess must equal Disabled. Anything else is reported as a finding with the evaluated property value attached as evidence.

How to fix it

Disable public network access to prevent unauthorized internet exposure. In Azure Portal: Data Collection Endpoint > Networking > set Public network access to Disabled. See: https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/data-collection-endpoint-overview

Careful: Disabling public access blocks all connections not routed through private endpoints or AMPLS

CLI

az monitor data-collection endpoint update --ids "{id}" --public-network-access Disabled

Terraform

resource "azurerm_monitor_data_collection_endpoint" "{name}" {
  name                          = "{name}"
  resource_group_name           = "{rg}"
  location                      = var.location
  public_network_access_enabled = false
}
